Abstract

Mangrove ecosystems are crucial in coastal protection, carbon sequestration, and biodiversity. Accurate mapping is vital for the conservation and sustainable management of these species, especially in vulnerable areas like Enggano Island, Indonesia. This study evaluates the performance of machine learning algorithms in GEE to model mangrove distribution on Enggano Island, Indonesia, using multi-source data, including optical data (Sentinel-2), radar data (Sentinel-1), and elevation data filtering (FABDEM). Three input configurations were developed to explore the best combination of data: (1) visual and infrared bands from Sentinel-2, (2) Sentinel-2 band ratios and spectral indices, and (3) a fusion of Sentinel-2 optical data with Sentinel-1 SAR data. Several machine-learning algorithms, including Random Forest (RF), Classification and Regression Trees (CART), Minimum Distance (MD), Gradient Tree Boost (GTB), K-Nearest Neighbor (KNN), and Support Vector Machines (SVM), were assessed using accuracy, precision, recall, and F1 score. Results showed that the third configuration, which combined Sentinel-2 optical bands, band ratios, and Sentinel-1 radar polarimetric, provided the best performance with the highest overall accuracy (OA 95.19%) using the Random Forest algorithm. This approach demonstrated superiority in overcoming mangrove classification challenges, such as cloud cover, seasonal variability, and spectral similarity with non-mangrove vegetation. These results support the importance of mangrove monitoring in small islands and tropical regions, contributing to ecosystem conservation and coastal disaster mitigation.

Abstract

This study examines the influence of Social Media Marketing (SMM) and Influencer Marketing on the consumer behavior of Generation Z (Gen Z) in Depok City, West Java. Utilizing a quantitative research approach, data were collected from 100 respondents through an online questionnaire. The findings from the multiple linear regression analysis indicate that both Social Media Marketing and Influencer Marketing significantly affect consumer behavior. Social Media Marketing, which is measured through variables such as content engagement, brand awareness, interactive features, and ad recall, has been shown to increase consumer engagement and influence purchasing decisions among Gen Z. Meanwhile, Influencer Marketing, which encompasses trust in influencers, influencer credibility, purchase intention, and content quality, plays a critical role in shaping the attitudes and behaviors of Gen Z consumers, leading to increased brand loyalty and purchase intentions. The study's coefficient of determination (R²) value of 78.1% suggests that these variables collectively explain the majority of the variability in consumer behavior among Gen Z in Depok City. These results align with previous research, underscoring the effectiveness of digital marketing strategies in shaping consumer behavior and offering valuable insights for businesses targeting Gen Z through social media and influencer channels.

Abstract

The rapid development of artificial intelligence (AI) technology is having far-reaching impacts on global economic, social and political aspects. However, the absence of universal ethical standards and regulatory gaps between developed and developing countries have posed serious challenges to fair and inclusive AI governance. Indonesia as the largest democracy in Southeast Asia is faced with a dilemma: responding to AI opportunities while ensuring ethical sustainability and digital sovereignty. This research aims to analyze Indonesia's normative and practical position in the dynamics of global AI governance, focusing on the regulatory dimension, political ethics, and participation in multilateral forums such as the G20, UNESCO, and ASEAN. A qualitative approach was used with methods of public policy analysis, official document studies (Personal Data Protection Bill, National AI Strategy), and interviews with technology experts and digital diplomats. The results show that Indonesia is still at an early stage in building a comprehensive AI regulatory framework, although it has shown commitment through strengthening its data privacy policy and national AI strategy. However, the absence of AI-specific laws and the lack of active engagement in global ethical governance frameworks are major obstacles in strengthening Indonesia's position as a normative actor at the international level.

Abstract

Gamifikasi telah muncul sebagai strategi ampuh untuk meningkatkan motivasi, keterlibatan, dan kinerja pelajar dalam lingkungan pembelajaran digital. Studi ini menerapkan kerangka kerja Gamifikasi Marczewski, yang menekankan tipe pengguna Achiever, untuk mengembangkan dan mengevaluasi platform persiapan TOEIC berbasis gamifikasi. Sistem ini menggabungkan poin pengalaman (XP), level, dan papan peringkat untuk mendorong kemajuan, menggunakan desain penelitian dan pengembangan. Sebanyak 120 responden berpartisipasi dalam implementasi percontohan, dan persepsi mereka diukur menggunakan kuesioner skala Likert yang menilai motivasi intrinsik dan ekstrinsik, keterlibatan pengguna, dan kepuasan. Statistik deskriptif menunjukkan tingkat motivasi intrinsik (M = 4,42, SD = 0,63) dan ekstrinsik (M = 4,47, SD = 0,49) yang tinggi, serta kepuasan pengguna (M = 4,80, SD = 0,46) dan keterlibatan (M = 4,15, SD = 0,71). Analisis statistik mengonfirmasi peningkatan signifikan pada semua indikator (p<0,05). Analisis data log menunjukkan bahwa 95% pengguna mencapai Level 11 atau lebih tinggi, dengan 90% menyelesaikan semua 12 level. Pembaruan pada papan peringkat menunjukkan lonjakan aktivitas, yang menunjukkan bahwa penambahan elemen kompetitif mempertahankan keterlibatan pengguna. Temuan ini menggarisbawahi potensi gamifikasi yang disesuaikan untuk mengoptimalkan persiapan TOEIC.
